Abstract
To provide a valve device that can reduce a pressure loss. A valve device according to the invention includes a housing in which an inflow port and outflow ports for a coolant are formed, a tubular valve which is housed in the housing and switches communication states between the inflow port and the outflow ports by rotating within the housing, and a frame attached to the inflow port and functioning as a flow passage for supplying the coolant to an internal space of the valve. Further, the frame has at least one rectifier which guides the coolant in a desired direction by bending the inflow direction of the coolant with respect to a rotary shaft of the valve.

A valve device comprising:
- a housing in which an inflow port and outflow ports for a coolant are formed;
- a tubular valve housed in the housing that switches communication states between the inflow port and the outflow ports by rotating about a shaft in the housing;
- and
- a frame attached to the inflow port,
- wherein
- the coolant passes through the frame and flows into an internal space of the valve, and
- the frame has one or more rectifiers that guide a direction of a flow of the coolant flowing in from the inflow port to a bending direction with respect to the shaft.
A valve device comprising:
- a housing in which an inflow port and outflow ports for a coolant are formed;
- and
- a tubular valve housed in the housing that switches communication states between the inflow port and the outflow ports by rotating about a shaft in the housing, wherein
- an introduction port for introducing the coolant into an internal space of the valve is formed at one end of the valve in a direction along the shaft, and
- one or more rectifiers that guide a direction of a flow of the coolant flowing in from the inflow port to a bending direction with respect to the shaft are provided in the introduction port.
